Here’s what HIVE AI had to say about “How long will the increased SALT cap remain in effect before reverting under the One Big Beautiful Bill?”:
Duration of the Increased SALT Cap Under the One Big Beautiful Bill
The increased State and Local Tax (SALT) deduction cap under the One Big Beautiful Bill represents a temporary enhancement to the current tax limitation structure. Understanding the specific timeframe and reversion mechanism is crucial for taxpayers planning their tax strategies in high-tax jurisdictions.
Temporary Enhancement Period
The One Big Beautiful Bill temporarily increases the cap on the itemized deduction for state and local taxes (SALT) to $40,000 from 2025 through 2029, subject to a phaseout for taxpayers with incomes above $500,000, then reduces the cap to $10,000 thereafter. Tax Foundation This creates a five-year window during which eligible taxpayers can benefit from the enhanced deduction limit, representing a fourfold increase from the current $10,000 limitation established by the Tax Cuts and Jobs Act.
The temporary nature of this provision means that taxpayers will have access to the higher $40,000 SALT cap for tax years 2025, 2026, 2027, 2028, and 2029. This timeframe aligns with the broader strategy of the One Big Beautiful Bill to provide temporary tax relief while managing long-term fiscal impacts.
Reversion to Previous Limitations
Beginning with the 2030 tax year, the SALT deduction cap will revert to the $10,000 limitation that was originally established by the TCJA. The economic analysis shows that the $40,000 SALT Cap (2025-2029) with a 30% phasedown to $10,000 SALT Cap over $500K income, followed by the $10,000 SALT Cap from 2030 onward, will have specific economic impacts including a -1.0% change in long-run GDP and affects approximately 488,000 full-time equivalent jobs. Tax Foundation
This reversion creates a significant cliff effect for taxpayers who have become accustomed to the higher deduction limits during the temporary period. The return to the $10,000 cap means that taxpayers in high-tax states will once again face the same limitations that were in place under the original TCJA provisions.
Strategic Planning Implications
The five-year duration of the enhanced SALT cap creates both opportunities and challenges for tax planning. Taxpayers in high-tax jurisdictions may need to consider accelerating certain deductible expenses or major financial decisions during the 2025-2029 period to maximize the benefit of the higher cap. Conversely, they must also prepare for the return to more restrictive limitations beginning in 2030.
The temporary nature of this provision also reflects broader fiscal policy considerations, as the major tax provisions in the Senate bill would reduce federal tax revenue by $5 trillion between 2025 and 2034 on a conventional basis, though on a dynamic basis incorporating projected economic growth, the dynamic score falls to $4 trillion, meaning economic growth pays for about 19 percent of the major tax cuts.

Interaction with Other Temporary Provisions
The SALT cap enhancement operates within a broader framework of temporary tax provisions in the One Big Beautiful Bill. The legislation includes various other temporary measures with different effective dates and durations, creating a complex landscape of expiring provisions that taxpayers and tax professionals must navigate.
The five-year duration aligns with the political and fiscal realities of tax legislation, providing meaningful relief while maintaining some fiscal discipline through the eventual reversion. This approach allows policymakers to provide targeted assistance to taxpayers in high-tax states while avoiding the long-term revenue costs associated with permanent changes to the SALT deduction.
Economic and Revenue Considerations
The temporary nature of the SALT cap increase reflects careful consideration of its economic and revenue impacts. The provision is designed to provide relief during a specific period while ensuring that the long-term fiscal trajectory remains manageable. The reversion to the $10,000 cap in 2030 helps limit the overall revenue cost of the provision while still providing meaningful benefits during the temporary period.
This structure also allows for future legislative consideration of the SALT deduction as the 2030 reversion date approaches, providing Congress with the opportunity to reassess the provision’s effectiveness and determine whether further modifications or extensions are warranted based on economic conditions and fiscal priorities at that time.
